This picture is a reworking of an alternative sketch for the Dragon's Lair:

The figures and Dragon were changed around, and I employed a different lighting scheme. The shafts of light help silhouette the Dragon's head and shine a spotlight on the main figure to create a focal point. Additionally 'spokes' of branches, spears, treasure, etc, guide our eye to the central action.

The knight is going to be impaled in the chest; the boy is going to be crushed by treasure; the girl is going to be ripped apart; the Spanish-conquistador-looking one at the back is going to be burnt to a crisp.
